Abstract
Many ceramics have been developed for the uses for mechanical or electronic parts. The high strength ceramic with reliability is necessary for the field of industtrial material. The purpose of this paper is to study relations between the power to function on the tool edge during cutting an alumina-green compact and the strength of sintered alumina ceramic. The strength of alumina ceramic was examined by the three point bending test. The main results obtained are as follows; (1) In cutting an alumina-green compact, destructive crack propagates along the grain boundary or transgranularly. (2) The true bending strength or the fracture energy of alumina ceramic decreases by the big power cutting of the alumina-green compact.
